3. The spring shown below is compressed 0.500 m and is used to launch a 100-kg student. The track is frictionless until it starts up the incline. The student's coefficient of kinetic friction on the 30.0-degree incline is 0.150. a) What is the student's speed just after losing contact with the spring? b) How far up the incline does the student go? k = 80,000 N/m m = 100 kg 10 m 30
